IMPROVEMENT IN IRONING APPARATUS.

Specification forming part of Letters Patent No. 166,648, dated August 10, 1875 application filed January 29, 1875.

CASE A.

To all whom fit may concern:

Be it known that I, HAMILTON E. SMITH, of the city, county, and State of New York, have invented a certain new and useful Improvement in Ironing-Machines, of which the following is a specification:

This invention is illustrated in the accompanying drawing, in which- Figure 1 represents a vertical section. Fig. 2 is a plan or top View.

Similar letters indicate corresponding parts.

This invention consists in the combination of a heated cloth-covered supporting-roller with two or more heated pressing-rollers running at a gradually-increasing speed, the superiicial speed ofthe Jrst pressing-roller being equal, or nearly so, to that of the supportingroller, while the superficial speed of the succeeding pressing roller or rollers differs more and more from that of said supporting-roller, in such a manner that the clothes, while passing through between the supporting-roller and the irst pressing-roller, are dried and pressed, and while passing through under the succeeding pressing-rollers they are finally dried and polished.

In the drawing, the letter A designates a frame, which forms Vthe bearings for the gudgeons a of the supporting-roller B. These gudgeons, as well as the roller, are hollow, so that said roller can be heated by steam, or otherwise. The supporting-roller is covered by a layer, b, of cloth or other suitable mate! rial, which is, by preference, fastened in such a manner that it can be readily removed when it becomes dirty, or whenever it is desirable to replace the same by another cloth. Over the supporting-roller B are placed a series (two or more) of pressing-rollers, C Cl Cz O3, which are hollow and provided with hollow gudgeons c, so that they can be heated by steam, or otherwise. The steam or heated air is introduced through a pipe, d, which communicates, by branch pipes e, with the pressi ing-rollers, and also with the supportingroller. The gudgeons c of the pressing-rollers have their bearings in boxes f, which are tted into slots g in the frame A, and which are subjected to the action of screws h, so that said pressing-rollers can be forced up against the supporting-roller with any desired degree of pressure. Said pressing-rollers are geared together with the supporting-roller, and their velocity is so adjusted that the superficial speed of the first pressing-roller C is equal to that of the supporting-roller, that of the second pressing-roller C1 a little greater than that of the supporting-roller, and so on, so that the clothes, as the same pass through between the supporting roller and the first pressingroller, are simply pressed, and at the same time partially dried by the heat of said rollers, and on passing through between the supporting-roller and the succeeding pressing roller or rollers the clothes are finally dried, and at the same time they are again pressed, and also exposed to a polishing action, produced on account of the increased speed ot' the second and the succeeding pressing-rollers. During the polishing action the clothes are prevented from slipping on the supportingroller by the ironing-cloth wrapped round the same; and, besides this, the irst pressingroller retains the rear portion of the clothes, while their front portion is exposed to the polishing action of the second pressing-roller, and so on. The clothes are fed to the apparatus over a table, D, which is secured on one end of the frame A, and they discharge over a chute, E, secured on the opposite end of said frame.

The difference in the speed of the pressurerollers is produced by belts or by intermediate gears-in the present example by means of gear-wheels m n o, each of which meshes with its own gear, lm. a o', mounted or formed on the wheel P of the shaft of the cloth-supporting roller.

What I claim as new, and desire to secure by Letters Patent, is

In an ironing-machine, the combination of a heated cloth-wound supporting-roller with a series of pressing-rollers, constructed to r o tate at different speeds, substantially as herein shown and described.

In testimony that I claim the foregoing, I have hereunto set my hand and seal this 25th day of January, 1875.
